Headline: "The [PLO] Department for Expatriates calls to the [Palestinian] communities to unite their efforts in a campaign to mark 100 years of the Balfour Promise (i.e., Declaration)"
"The PLO Department for Expatriates emphasized… in a letter that it sent to the Palestinian communities in foreign countries… that one of the conditions for the success of the campaign, which is expected to last from Nov. 2, 2016 to Nov. 2, 2017, is its reliance on the national consensus plan led by the PLO. It noted that they must not be satisfied with publication of notices of condemnation, but rather must act to take advantage of the international momentum that supports the Palestinian people in order to accumulate achievements for the right of the Palestinian people and for the right of its cause… The department emphasized the supreme importance of setting clear goals for the campaign, and primarily a call to turn 2017 into the year of the establishment of the Palestinian state and to demand of Britain that it apologize for the Nakba (i.e., “the catastrophe,” the Palestinian term for the establishment of the State of Israel) and the suffering that it [Britain] caused the Palestinian people, and [that it] atone for the crime that it committed by recognizing the Palestinian state."

The Balfour Declaration of Nov. 2, 1917 was a letter from British Foreign Secretary Arthur Balfour to Baron Rothschild stating that “His Majesty's government views with favour the establishment in Palestine of a national home for the Jewish people” and is seen as the basis for later international commitments to establish the State of Israel.
